Operation; Cleaning And Maintenance; Replacing The Fuse - Omnitronic MPS-1250 User Manual

The device must only be connected with an electric installation carried out in compliance with the IEC-
standards. The electric installation must be equipped with a Residual Current Device (RCD) with a maximum
fault current of 30 mA.

OPERATION

After having connected your amplifier to the mains, turn the volume control counter-clockwise to Min-
position. The last device to be switched on is the amplifier. Adjust the volume with the volume control.
Caution! Increase the level of each channel only so far that the CLIP-LED lights up shortly. Thus, you avoid
that the output signal is distorted and your speakers are damaged.
When operating the speaker-system, please make sure that the loudspeakers always sound well. When
distortions can be heard, either the amplifier or the loudspeaker is overloaded. Overloads can quickly lead to
amplifier or speaker damage.
In order to avoid damage, please reduce the volume immediately when distortions can be heard. For
speaker-systems destroyed by overload the guarantee becomes void.
Always check the sound pressure level with a meter in order to keep to the threshold.
If you want to switch off the system, switch off the amplifier first and then the pre-amplifiers in order to
avoid acoustic shocks on the speakers.

CLEANING AND MAINTENANCE

We recommend a frequent cleaning of the device. Please use a soft lint-free and moistened cloth. Never use
alcohol or solvents!
There are no serviceable parts inside the device except for the fuse. Maintenance and service operations are
only to be carried out by authorized dealers.
